A wealthy elderly couple die together in an accident. Soon a man shows up to claim their fortune, saying that he is their only son who ran away from home as a boy. Other relatives dispute his claim. Hospital records show that the deceased couple were Type AB and O. The claimant to the fortune is Type O. Could he be their son? Explain. In plants known as "four-o-clock", the allele for the dominant red-flower is incompletely dominant over the allele for white-flower. A gardener allow several heterozygous pink-flower self pollinate and collect 200 seeds. What is the theoretical percentage of the phenotypes resulting from this cross.

Use fto represent the recessive allele for cystic fibrosis and Ffor the allele for the unaffected condition. Use A to represent the dominant allele for normal melanin man is albino and heterozygous for cystic fibrosis. His wife has the unaffected phenotype for both traits, although her father had cystic fibrosis and a for the recessive allele for albinism. and her mother is albino. 4a.

11. Blood type is controlled by a gene with multiple alleles. A produces type A blood. B codes for type B blood. A and B are codominant so a heterozygote has type AB blood. The O allele is recessive to both A and B and produces type O blood. A. What are the possible genotypes of a man with type A blood? AA or AO B. What are the possible genotypes of a man with type B blood? BB or BO C. Can a man with type B blood be the father of a baby with type O blood? Why or why not? Explain your answer. If the man has blood group B than it's genotype can be BB or BO. If the man has BO blood group and the woman he marries is either AO,BO or OO blood genotype than only the man can have a child with O blood group type. Because the child will receive O allele from both the parents as O blood group type is only dominant when it's in pair because it's a recessive allele. D. A man with type A blood marries a woman with type B blood. What blood types are possible for their…
3. A couple just had a baby, who has type-O blood. Upon learning the baby’s blood type, the father becomesinfuriated and accuses the mother of cheating on him. The mother has type-A blood and the father has type-Bblood. Knowing that the allele for type-O is recessive, answer the following questions.a. What is the relationship between the IA, IB, and i alleles?b. Is the father right? Or is he falsely accusing the mother? Explain. Include the genotypes of the parentsand the genotypes of their potential children.
1. Count out 60 black beans and 40 white beans into the baggie. Let the black beans represent the dominant allele A, and the white beans represent the recessive allele a, in the gene pool. This is your F0 generation. 2. Without looking, randomly remove two beans from the baggie. This represents one diploid individual offspring in the next (F1) generation. Tally the diploid genotypes of the offspring formed by these two gametes in Table 1 below. 3. Return the two beans back to the bag and gently shake it to reinstate the random gene pool. By returning the beans after each selection, the size of the gene pool remains constant and the probability of selecting any allele should remain equal to its frequency in the gene pool. Repeat this 50 times, meaning 50 individual diploid organisms. 4. Make sure to return all beans to the baggie. 5. Repeat this procedure (steps 2-3) (for your F2 generation) until you have recorded the genotypes of another 50 individuals.

1. A mother with blood type A has a child with blood type O, and she claims that Mister X is the father. Mister X denies that he could possibly be the father, because he has blood type B. If you were the judge presiding over this case, which of the following arguments would you find most convincing? a. Mr. X could be the father if his blood genotype is IBIB, and the mother’s blood genotype is IAIA b. Mr. X cannot be the father because a child with blood type O cannot have a parent with blood type B c. Mr. X could be the father if his blood genotype is IBi, and the mother’s blood genotype is IAi d. Mr. X cannot be the father because a parent with blood type B cannot have a child with blood type O e. Mr. X cannot be the father because the human ABO blood types are sex-linked traits 2.
